SPRING BED-BOTTOM.

SPECIFICATION forming part of Letters Patent No. 297,868, dated April29, 1884. Application tiled May 7K, 1883. (No model.)

To all whom t mayA concern:

Be it known that I, DAVID F. STAMBAUGH, acitizen of the United States,residingat-Effingham, in the county of Eflingham and State of Illinois,have invented certain new and useful Improvements in Bed-Bottoms; and Ido hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to certain improvements in spring bed-bottoms;and it has for its objects to provide a spring bed-bottom that will becheap and simple in construction, and which will accommodate itself tothe weight of the occupant, as more fully hereinafter specified. Theseobjects I attain by the means illustrated in the accompanying drawings,in which- Figure 1 represents a partial plan view of my improvedbed-bottom, and Fig. 2 a longitudinal vertical sectional view thereof.

In the drawings, the letter A indicates a rectangular frame, thetransverse end bars of which are set at an angle, as shown in Fig. 2 ofthe drawings. About midway between the ends of the longitudinal rails Bare secured the transverse slats C, upon which are secured the spiralsprings D, which support the longitudinal slats E. The springs at theirtops are connected together by means of links E', the springs at eachside being" connected to the side slats by means of suitable clips, F.The

longitudinal slats are connected to each other by means of the cords G,and the springs arek connected to the cords by lateral extensions H, asindicated by dotted lines in Fig. 1 of the drawings. Thesaidlongitudinal slats at their ends are connected to the end rails of theAframe A by means of spiralsprings I, secured to the frame by screws orotherwise, as indicated. The spiral springs are connected at their topsby means of links B.

It will be seen Lthat as constructed when the occupants weight is lightthe tendency will be to depress the upright spiral springs below theslats; but as the weight increases the tendency will be to draw upon theend springs, thus i secured to said springs, the cords G, connecting theslats, and the longitudinal spiral springs I, connecting the slats attheends to the frame, substantially as and for the purposes specified.

- In testimony whereof I affix my signature in presence of twowitnesses.
